BALL-BEARING.

Specification of Letters Patent.

Patented Nov. 17, 1914.

(Jontinuation of application Serial )lo. 655,652, filed October 18,1897. This application filed April 6, 1910. v, Serial No. 553,897.

My invention relates to ball holding de vices, andparticularly to thatclass o't'ball bearings wherein a holder is used, havinga series of ballbearing points to retain the balls, the latter projecting'beyond'thedevice, in the inner and outer, and in .the upper directions withrespect thereto, and it has for its object the provision of anorganization of the class described, simple in construction, inexpensiveto manufacture, and which operates in a smooth, easy and noiselessmanner in practical use.

To attain the desired end, this, my invention, consists in theconstruction, arrangement and operation of the parts herein set forth.

In the drawings which accompany and form apart of this specification,Figure 1 my ball retaining devices; and Figs. 9 and.

10 are respectively views of blanks of which the retaining devices shownin Figs. 2 and 6 are made.

Like letters of reference indicate like parts in all the views.

I have found it desirable to devise a ball bearing of simp econstruction, and one that will be reliable and efiicient, as well asnoise less, in practical use, in which the balls are held in theirnormal positions by means of a retaining device, and I have, therefore,constructed according to my invention, an organization of the kind setforth, embodyin}; the preferred construction of parts and their mutualrelationship, combination, arrangement and organization in a compositebody or structure, as hereinafter described.

Referring particularly to the drawings. A

denotes y ball holding device located in the chamber formed by the innerflanges of) y i the hub A-',-and the cones of'the axle A,

inner and outer-bearing points In the embodi ment illustrated in thesefigures the edges cities the walls of the recesses A formed between theupper portions A of the ring, are preferably parallel with each other,and the same extend upward above the center line of I the balls B; theside walls a of the'same,

these intermediate portions in thisinstance e rtending radially ortransversely of tliefj' rlng, in'connection with ,the bottom portion ofsaid ring, constituting the recesses Af" which walls a are preferablyinclined to-' ward the balls in order that the upper por-' tions of eachrecess will be somewhat smaller than the lower part thereof. My bearingpoints or detents consist, in this instance, of one or moreverticalprongs, as a in Fig. 3, located in the inner and outer poi,- tions ofthe recess A", or lateral prongsfas' o in Fig. 4, located along theinner and? outer edges of the side inclined portions of my ring A. Ifpreferred,-however, the. parts of my ring, forming the lower portions off Said y be of circular f rm, 5 A shown in Fig. 5, or they may be rectangulari as Flgs- 6 and constitutin g the recesses A, and to the upperportions, as A, of my ring, as in Figs. 6 and 7, may

be secured, as by pins a, supplementary platesA, provided withprojecting retain ing portions or pointsa, formed by. the.

same being laterally recessed or 'concaved,

the said top portions being wider at their outer edge than at the inneredge thereof.

It will be apparent from a consideration of the several forms of myinvention illustrated and described that it comprises a ring-shapeddevice having a base portion that serves as a support upon which. reststhe series of balls, that from this base portion of the retainer thereare bent up a series of members designated a. in the drawings. andtermed herein side walls, as they serve to separate from each other therecesses in which are confined the individual. balls. though thesemembers may also with propriety be termed standards or flaps, and

- stantially parallel with the base portionsof the retainer and inangular relation to the side walls (otherwise termed standards or flaps)that rise therefrom, so that: they extend outward from. the sidewallsmore or less over. the recessesjo'r the balls, the latter beingretainedinthe-holder whenit is'removed from the ball raceor bearing.

The side wallsa stotherwise termed standardsor flaps) that risefrom thebase may be erpendicular thereto, as indicated-in F ig; g or inclinedthereto, as-representedin Figs. 3, 4 and 5swhilethetop retainersscarriedby the saidside walls maybe-integralthere;

with, 'as indieatedinz'Figs, 4, 5,, Band- .7-, m

of a compound two-part nature, including plates secured who thetop-upor'tions .asindicated in Figsafi and .7 a-Eusthep, the edges ofthe top retainers that bound-the recesses in which are.situated-theg-balls -meyqbe straight and substantially parallel witheach I other, as indicated in Fig. 4, or they may be of a substantiallyconcave contour, as indi cated in Fig. 6, this latter construction forsome purposes being the one which I prefer. In both constructions,indicated respectively in Figs. 2 and 6, the'top retainers extendoutwardly, that is, they are radially disposed (each considered as awhole extending from a position substantially over the inner edge of thering to a position substantially over the outer edge thereof, and theyare each laterally enlarged, that is, each portion or extension islarger or wider at its outer portion than at its inner portion. Thisconstruction results in the production of a topretaining member for theballs having sharp corners or pointed ends. When these top retainers areconstructed as-indicated in Fig. 6, that is, with the-edges that boundthe 'ball recesses made concave, the pointed edges thereof areemphasized, as indicated ata in Fig, 3. The advantages incident to thislatter construction arise from the fact that by 'concaving the oppositeedges of the top retaining extensions the balls are allowed to projectupward, that is, away from the base support, and out of their recesses,to a greater extent than where .the opposite edges are straight, asindicated in Fig. 2. When the holder is formed as indicated in Figs. .8and 9, the parts of the top retainers designated A extend outward fromthe side walls (otherwise termed standards'or flaps), as clearlyindicated in Fig. 7, so as to lie over and retain the balls.

It is manifest that various omissions of some -particulars could be madewithout materially aifecting theessential-features of yond the same .inthe inner and ,outer'and,

in the upper directions, The ballsare thus securely held in place, andby means of the construction. shown, are allowed to move quite a longdistance radially, and they are thus enabled to adjust themselves, incase of any. wearing of thebearing taking place, the side bearingpoints, "asstated, preventing the balls from rolling'ou't oftheirsockets, in either-asvertical, radial or lateral direction, which ballsmay be readily snapped in and out of the-retainer,.at will.

Obviously, my ball retaining device-may be advantageously employed inmany kinds of hearings .or sockets, and I do not therefore wish to limitmyself to the use of my device in connection with ball bearings of thekind shown alone. I

As it'is evident that many changes in the construction and relativearrangement of parts might .be resorted to ,without departing from thespirit and scope of my invention, I would have it understood that I donot restrict myself to the particular construction and arrangement ofparts shown and described, but that such changes and eguivalents may besubstituted therefor, and t at What I claim as my invention, is z 1. Anannular ball-holding device COIDr;

prising supporting means for balls, intermediate portions projectingupwardly from the said supporting means in approximately radialdirections, and top retainersjoining the supporting means and projectingsome what over a part of the surfaces of the balls.

prising a base constructed and arranged to support the balls, topportions extending substantially parallel to the base, inter-. the baseandtop.

2. An annular ball-holding device comthe intermediate portions andoverhanging F ries of upwardly extending parts, and also concaved.

5. A ball-retaining device for ball hearings consisting of a ringcomprising a se ries of upwardly extending parts, and also a series ofpractically horizontally-positioned parts superimposed over the ring,the said practically horizontal parts being wider at their outer edgethan at the inner edge thereof, and having at the outer and inner edgesof the same points projecting into the ball holding recesses.

6. A ball-retaining device for ball bean ings consisting of a ringcomprising a series of upwardly extending parts, and also a series ofpractically horizontally-positioned parts superimposed over the ring,the

said practically horizontal parts being Wider at their outer edge thanat the inner edge thereof, and having the side edges of the sameconcaved, and having at the outer and inner edges of the same pointsprojecting into the ball holding recews.

T. A ball-retaining device for ball bear ings consisting of a ringcomprising a series of upwardly' extending parts, and also a series ofpractically horizontally-posh tioned parts superimposed over the ring,the said practically horizontal parts having the side edges of the sameconcaved.

In testimony of the foregoing specification. I do hereby sign the samein the city of New York, county and State of New York, this second dayof March, 1910.
